im using the alum. mastercool with 4 port ball valves at this time
but they are too heavy & appear to be leaking past the ball valves.
im in line for the brass manifold & when it is released you can rest assured it will be perfect. he has new product he is working on that will blow your mind away.
i saw the ak900 at the las wegas ahr show,looks nice,taking place of drsa1250,priced under 300
At that price and with Digi-Cools reliability in producing quality instruments that can also compete with Testo and others on price. That is a true winner for Doug and all of us in the in the industry!!
